Model 347 Pressure Transmitter

4-20 mA output, 0-3 to 20K psi

347 offers a solid, reliable pressure transducer with excellent noise immunity, repeatability and stability.


 All Stainless Steel construction


Model 347’s are found in oil and gas, hydraulic control, test and many other applications requiring stable and reliable pressure measurements with good accuracy at a fair price.  They can be configured in a variety of ways – from a sealed housing with a cable to allow it to be used in outdoor environments to a unit ranged to allow for high pressure spikes with a solid machined diaphragm.  We welcome your inquiries to provide you with a solution tailored to your needs.
